your package ran a command that returned a non-zero exit code. you didn't include what the command was. you could try attaching the complete bldeploy log that you pasted the snipped from using the advanced editor in the post.
BLPackage deploy job fails with the exit code 11 as below. Agent info is good. Job is successful on simulate and stage,
all of which are irrelevant here.
Thanks for your reply Bill, This got successful after ACL push.
